Re: 5.4.5 to 7.1 upgrade questions using IMGCLG ?

"It Depends" (as usual!)

If you have sufficient Arms (NOT GB!) then Image catalogs will be very much faster plus you don't have to feed disks to the machine.

If you have few arms, physical media will win because the reading and the writing is from/to the same overloaded arms.

So how many is "enough"? I generally say 8 Arms is good to go with Image catalog. 4 arms is not enough. In between there it could go either way.

Is there any big difference in installation time using catalogs 'vs'
physical media.
